It is to make purpose, technical scheme and the advantage of this utility model embodiment clearer, new below in conjunction with this practicality
Accompanying drawing in type embodiment, is clearly and completely described to the technical scheme in this utility model embodiment, it is clear that retouched
The embodiment stated is a part of embodiment of this utility model, rather than the embodiment of whole.Based on the enforcement in this utility model
Example, the every other embodiment obtained under the premise of creative work is not made by those of ordinary skill in the art are belonged to
The scope of this utility model protection.
As shown in figure 1, the present embodiment is related to a kind of device for identifying pcb board, including pcb board control unit 2 and PCB
Panel sign circuit 1；As shown in Fig. 2 pcb board marker circuit 1 is included between high level and low level is parallel with least even number bar
Series circuit, includes the different first resistor of the resistance being sequentially connected in series between high level and low level in every series circuit
RA_0-RA_5 and second resistance RB_0-RB_5；First resistor RA_0-RA_5 and second resistance RB_0- in every series circuit
Between RB_5, the magnitude of voltage BID_0-BID_5 of junction is delivered to analog-digital converter 4 in pcb board control unit 2, analog-digital converter
4 output valve is stored in the memorizer 3 of pcb board control unit 2.The level commonly used in electronic product is 3.3V and 5.0V.This
Embodiment high level is 3.3V, and low level is that ground, i.e. second resistance RB_0-RB_5 are connected on first resistor RA_0-RA_5 and ground
Between.
Specifically, as shown in Fig. 2 pcb board marker circuit 1 includes 6 series circuits of parallel connection, example in the present embodiment
Such as, first series circuit includes first resistor for RA_0 and second resistance RB_0 of series connection with it.By changing first resistor
The resistance of RA_0-RA_5 and second resistance RB_0-RB_5, obtains different magnitudes of voltage at the BID_0-BID_5 ends, when first electric
RA_0 is when for 0 Europe, second resistance RB_0 has resistance for resistance, and voltage BID_0 at is 3.3V；Have resistance when first resistor RA_0 and
When second resistance RB_0 is 0 Europe, the voltage at BID_0 is 0V；When first resistor RA_0 has resistance and second resistance RB_0 also has
During resistance, the voltage at BID_0 is the magnitude of voltage between 0V-3.3V.Control source at BID_0 is to analog-digital converter 4, example
Such as, the voltage threshold being previously set according to pcb board control unit 2, when the voltage at BID_0 is in voltage threshold, by BID_0
When the magnitude of voltage at place is more than threshold value by the voltage at 0, BID_0 of numeral is output as after analog-digital converter 4, at BID_0
Magnitude of voltage is by being output as numeral 1 after analog-digital converter 4.Similarly, the magnitude of voltage at BID_1-BID_5 passes through analog digital conversion
Numeral 0 or 1 is output as after device 4, then BID_0-BID_5 can export a series of digital signals, example by analog-digital converter 4

000111.Intuitively check which design phase used pcb board belongs to for convenience, as shown in figure 1, display unit 5 and PCB
Plate control unit 2 connects, and the display module in display unit 5 reads the data 000111 in memorizer 3, and data are divided into
Two groups of data：Data 000 and 111 are being processed by first group of data 000 and second group of data 111（Such as high-order cover）
Afterwards, first group of data 000 is processed into 00000000 and second group of data 111 is processed into 00000111, thereafter through with PCB
First group of data 00000000 on the display screen of display unit 5 is shown as ten and is entered by the display unit 5 of the connection of plate control unit 2
Number processed 0, and second group of data 00000111 is shown as into decimal number 7 on the display screen of display unit 5, it is current so as to record
The state of the design phase of the pcb board for using is 07.Therefore, when pcb board marker circuit 1 includes 6 series circuits of parallel connection
When, the design phase of 64 kinds of pcb boards can be represented.Certainly, 8 series electricals in parallel can also be included in pcb board marker circuit 1
Road or other suitable even number bar series circuits.
Sexual behavior mode is substituted as the another kind of of design phase of mark pcb board, storage is read with converting unit 6 by reading
Data in device 4, such as 0001111, and data are divided into into two groups of data：First group of data 000 and second group of data 111,
Data 000 and 111 are being processed（Such as high-order cover）Afterwards, first group of data 000 be processed into 00000000 and second
Group data 111 are processed into 00000111, and first group of data 00000000 is changed into ten's digit 0 by program then, and
Second group of data 00000111 is changed into into ten's digit 7, therefore by reading the working as the pcb board for using with converting unit 6
The state representation of front design phase is 07.It is of course also possible to pass through the combination digital-scroll technique 07 of decoder and charactron.When low electricity
When putting down the level for non-zero, the binary digital signal of the output of analog-digital converter 4 is obtained using as above similar approach.
Device for identifying pcb board of the present utility model：The device circuit simple structure, it is easy to accomplish and manufacturing cost

The resistance of first resistor RA_0-RA_5 and second resistance RB_0-RB_5 of series circuit in panel sign circuit 1, and then can be with spirit
The magnitude of voltage for changing second resistance RB_0-RB_5 living, the difference two for obtaining being stored in memorizer 3 by analog-digital converter 4 enter
Signal processed, different binary signals represent the different design stage of pcb board, the binary signal can by software read or
The corresponding decimal value of the binary signal is shown, the current design stage of the pcb board for using conveniently is checked, not by pcb board
Packed impact, realizes quick, reliable and accurately identifies.
Finally it should be noted that：Above example only to illustrate the technical solution of the utility model, rather than a limitation；
Although being described in detail to this utility model with reference to the foregoing embodiments, it will be understood by those within the art that：
Which still can be modified to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, do not make the essence of appropriate technical solution depart from each embodiment technology of this utility model
